to be honest a bmx brake is only as good as its pads
ive had ad990's, tektro's, fly cnc brakes, proper cnc brakes and a revenge sealed bearing brake
and they all were as good as each other it was the pads that made the difference
my textro with clear pads works better than my old fly brake with kool stop pads on the front
really all it comes down is what design you prefer, as said my textro works great it just looks crap in my eyes
a set of clear pads cost £5-£7 and they make a big difference
